How to add additional methods for User?

Question

Django

You need to add additional methods (not fields) for the standard User. How to do this so that you can access through the model itself, such as

request.user.method_name() или User.objects.first().method_name()

Answer 1

Making a custom user when creating a new project is the first task for 95% of projects. And there you can hang as many methods as you want.
If this is no longer possible - monkey patching.
